RESUMO
Myeloid sarcoma is a very rare extramedullary malignant tumour, most often associated with acute myeloid leukaemia. We report the case of a man in his early 20s who presented with chronic headache, raised intracranial pressure and progressive vision loss of 2 years duration with no systemic manifestations. He had a history of myeloid sarcoma of the left thigh 15 years ago, treated with external beam radiotherapy and in complete remission for more than 13 years. However, the progressive blindness remained unexplained for 2 years, and he was eventually diagnosed with isolated meningeal relapse without marrow or systemic involvement. Imaging revealed subarachnoid haemorrhage, diffuse leptomeningeal enhancement and involvement of lower dorsal cord and conus, and cerebrospinal fluid cytology showed myeloid blasts. He was managed with intrathecal chemotherapy and craniospinal irradiation, after which he had mild improvement in vision.

ABSTRACT: Congenital myasthenic syndromes (CMS) are relatively rare neurologic syndromes of defective neuromuscular transmission that stem from mutations in various proteins at the myoneural junction. Classically, the patients present within the first 2 years of life; however, the disease can also have onset in the second or third decade of life. The disease characteristically involves the skeletal muscles and spares smooth and cardiac muscles. The patients present with weakness involving ocular, limb, axial, or bulbar muscles. The specific diagnosis in most cases is clinched by genetic testing. We report a 59-year-old man presenting with neuromuscular weakness for 3 years and calf hypertrophy. He had myopathic features on electrophysiologic studies with a decremental response on repetitive nerve stimulation. Genetic testing confirmed a diagnosis of DOK7 CMS. He was managed with salbutamol and showed significant improvement.

Too little is known about DMJD in adults. Various phenotypic presentations in adults with DMJD and long-term follow-up is needed to further characterise this disease.

Wunderlich syndrome is a rare condition characterised by acute spontaneous non-traumatic renal haemorrhage into the subcapsular and perirenal spaces. Our case of anti-GAD65-associated autoimmune encephalitis (AE), aged 30 years, developed this complication following use of enoxaparin and was managed by selective glue embolisation of subsegmental branches of right renal cortical arteries. Our case had opsoclonus as one of the clinical manifestations, which has till now been described in only two patients of this AE. This patient received all forms of induction therapies (steroids, plasmapheresis, intravenous immunoglobulin and rituximab) following which she had good improvement in her clinical condition. The good response to immunotherapy is also a point of discussion as this has been rarely associated with anti-GAD65 AE.
